This invention relates to a. device for pressing small articles such as neckties, collars, handkerchiefs and the like, and has fol an objectthe provision of means whereby such articles maybe pressed by feeding the articles into the machine afterhaving set the machine in operation by dropping a coin therein.

Another object is to provide means whereby an article to be pressed may be moistened and dried as the pressing operation is performed.

Another object is to provide a simple and efiicient coin actuated means for setting the mechanism of the device in operation.

Another object is to provide a device for the purposes stated which may be easily kept clean, thereby precluding soiling of articles pressed therein.

'20 .Another object is to provide a device for the purposes stated which is simple of operation and which may be cheaply operated and manufactured.

These and other objects are attained by the means described herein and disclosed in the accompanying drawings in which:

Fig. 1 is a perspective view of the device, parts being broken away. 1 Fig. 2 is a front view of the device shown in Fig. 1, the front cover thereof being removed.

Fig. 3 is a sectional view on line 33 of Fig. 2. a

F Fig. 4 is a sectional view on line 4-4 of ig. 5 is a view of a wiring diagram of an electrical circuit used in the device.

The coin operated pressing device of this invention comprises a casing 9 for housing the various operating mechanisms for controlling a-nd actuating a pair of pressing elements, which may be in the form of rollers 10 and 11 one of which is adapted to be electrically heated. The pressing elements or rollers are adapted to receive therebetween an article to be pressed, as exemplified at 12.

The means for actuating said rollers will be described later. Outside the casing and securedto the front wall 13 thereof is a mois- 5 tening means comprising a fluid container 1927. Serial No. 192,361.

14 which may be of porcelain or glass or other suitable material. Disposed within the container is a freely rotatable cylinder 15 which is preferably corrugated as at .16 and which is partly immersed in a fluid 17, which may be water or, if desired, a treated solution. A cover 18 for the fluid container 14 is provided with brackets 19, and with an opening 20 through which the cylinder 15 may project. A smooth weighted cylinder 21 is provided with stud shafts 22 which are received in an elongated slot 23 in each bracket 19. The cylinder 21 is freely rotatable and rests upon the corrugated cylinder 15. It is obvious that by lifting the cylinder 21 and lacing an article to be pressed such as 12 etween the cylinders, the article 12 may be moistened by being drawn therebetween, the cylinders rotating and cylinder 15 supplying fluid from the-container 14.

As shown in Fig. 3, the rollers 10 and 11 rotate in opposite directions as indicated by. the arrows, wherefore the article 12 to be pressed is obviously drawn therebetween and is ejected from a tube 24 extending through the lower wall 25 of the casing. Aperture 26 in wall 13 permits access of the article 12 to the rollers.

Pressing element or roller 10 comprises a wrapping or tube of felt or other resilient material 27 disposed about a two piece shaft 28, one section 29 of which is provided with a threaded extension 30. A corresponding threaded bore 31- in section 32 receives the extension 30 which may be screwed thereinto for decreasing the distance between flanges 33 and 34 on sections 32 and 29 respectively, for compressing the felt wrapping 27 therebetween. Ends 35 of shaft 28 are journaled in the side walls 36 and 360 of the.casing, for supporting roller 10.

Roller 11 is a comparatively light gauge metal cylinder provided with stud shafts 37 and 38 each having a bore 39 adapted to receive a tubular insulator 40. The bore in each tubular insulator supports a conductor of electricity 41. Electrically connected to each conductor 41 is a resistance wire or other heating element 42 (Fig. 4), which is housed within the roller 11 and which serves to heat said roller when connected with a source of electricity. The conductors, insulators, and

stud shafts are tightly fitted and rotate as a unit in elongated bearings 43 in side walls 36 and 360. Wires 44 and 45 are electrically connected to said conductors by any suitable means such as pivotal or swivel connections 46 which preclude twisting or breaking of the wires 44 and 45 as rotation is imparted to roller 11. Suitable covers 47 are provided for enclosing the wires and'their' swivel connections.

Means are provided for yieldingly urging the pressing element or roll 11 toward roll 10. Said means comprises a pair of vertically movable bearing blocks 48 adapted to be I urged yieldingly upwardly by means of springs 49, as shown in Fig. 4. Looks 48 are provided with elongated perforations 50 adapted to receive shafts 37 and 38 of roller 11, which shafts have a bearing on the said blocks 48 at 51. It should be noted also that flanges 33 and 34 on roller 10 abut the shafts 37 and 38 for limiting the clearance between the pressing surfaces of the rollers.

Means are provided for imparting rotatory motion to roller 11, said means comprising a sprocket 52 on shaft 38 about which a adapted to be actuated by dropping a coin.

- chain 53, driven from a second sprocket 54,

therein. The coin, dropping into the inside thereof, actuates a mechanism which closes an electrical circuit to the motor for starting the motor whereby roller or pressing element 11 is rotated. At the same time, an electrical circuit through the heating element 42 of roller 11 is closed, which energizes element 42 for heating the roller 11. Roller 10 is rotated by reason of the frictional contact thereof with article 12.

The coin actuated mechanism will now be described with reference to Figs. 2 and 5.

Pivotally mounted at upon a bracket 66 is a lever 67 having ends 68 and 69. End 68 is weighted so asto normally dispose'the lever asindicated by the dotted lines in Fig. 2. An

electro-magnet 71 is secured upon a bracket 69 on side Wall 36, and'is disposed directly above weighted end 68, which is of magnetic material. It is obvious that when the electro-magnet is energized, it will attract the end 68 and retain it in the operative position shown by full lines in Fig. 2. Bracket 69 also carries an electrical contact member 72 which is insulated therefrom, and lever 67 carries a like contact 73, insulated from the lever.

Above the end 69 of lever 67 is a coin chute 74. A coin dropped into the chute will strike the end 69 of the lever and rotate it about the ment 42 which are connected in parallel, as shown in Fig. 5. It should be noted also that the lever will remain in this position as long as the electro-magnet remains energized. Means are therefore provided for breaking the circuit through the said energized elec-' trical fixtures.

The means for breaking the electrical circuit comprises a trip 75 on the chain 53. Upon a complete revolution of-the chain 53, the trip abuts the end 69 of lever 67, carrying the end upwardly until said end strikes the coin chute as shown in the dotted lines. The circuit has then been broken, and trip 75 slides over the end of the lever and is carried by the momentum of the motor to theposition indicated by dotted lines. The mechanism is then in position to receive another coin. The coins drop from the chute into a compartment such as 76 to which access may be had through an opening provided with a hinged door 77 having a suitable lock 78.

To facilitate mountingthe device on a wall or the like, a series of perforations 79 for receiving fastening means are provided in the rear wall of the device. ductors 44 and 45 may extend without the casing at any convenient place, depending on the manner or means by which it is desired to make connections to a main current supply line.
